A police report says Apperson had a fixation on the former neighborhood watch leader and that Apperson had recently been admitted to a mental institution before his run-in with Zimmerman earlier this month.

A hearing on the matter is set for Friday.

Zimmerman and Apperson had a previous road-rage encounter last September, when Apperson alleged that Zimmerman had threatened him. No charges were filed.

Zimmerman was acquitted of any crime two years ago for fatality shooting unarmed black teen Trayvon Martin — a case that sparked protests and a national debate about race relations.
